摘要： An entertainment system comprises circuitry configured to receive input signals from at least a first input device and a second input device, wherein each input signal corresponds to a control in one of the input devices, determine whether each input signal is included in a respective control subset allocated to the input device from which the input signal was received, determine if each input signal is an input signal to be utilised based on whether it is included in the respective control subset, treat input signals to be utilised from any of the input devices as input signals from the same single input device, and determine, according to a predetermined control scheme, a process to be executed based on the input signals to be utilised, and wherein the respective control subsets each comprise at least one control not found in the other control subsets, and the respective control subsets together comprise a full complement of controls for an input device.

摘要： A method of environment mapping comprising the steps of receiving a plurality of images from respective different viewpoints; using a simultaneous localisation and mapping 'SLAM' process, detect feature points in the plurality of images; classifying one or more objects within the plurality of images as being objects of interest; determining the position of the or each object of interest using feature points corresponding to the objects of interest in the images; and providing an indication of the position of one or more objects of interest to a user of a virtual display; and wherein the step of determining the position of the or each object of interest using their feature points is repeated, more frequently than for other feature points in the images.

摘要： A method of recording a seamless customised video recording of a video game, the method comprising the steps of: video recording a first run-through of at least a part of the video game; saving a saved-game state of a first game state of the video game, the saved-game state enabling a game state of the video game to be reset to the saved-game state that is at least visually identical to the first game state; detecting, in response to the saving of the saved-game state, a time within the video recording of the first run-through corresponding to the time the saved-game state is saved; video recording, when the game state is reset to the saved-game state, another run-through from the saved-game state; and editing the video recording of the first run-through by replacing some or all the video recording of the first run-through recorded from the detected time with the video recording of the other run-through when the other run-through meets a predetermined preference criterion.
